Visual Attention in Brains and Computers by Massachusetts Institute of Technology( Book )

2 editions published in 1986 in Undetermined and English and held by 2 WorldCat member libraries worldwide

Existing computer programs designed to perform visual recognition of objects suffer from a basic weakness: the inability to spotlight regions in the image that potentially correspond to objects of interest. The brain's mechanisms of visual attention, elucidated by psychophysicists and neurophysiologists, may suggest a solution to the computer's problem of object recognition
Learning a color algorithm from examples by Massachusetts Institute of Technology( Book )

2 editions published in 1987 in English and held by 1 WorldCat member library worldwide

We show that a color algorithm capable of separating illumination from reflectance in a Mondrian world can be learned from a set of examples. The learned algorithm is equivalent to filtering the image data-in which reflectance and illumination are intermixed-through a center-surround receptive field in individual chromatic channels. The operation resembles the retinex algorithm recently proposed by Edwin Land. This result is a specific instance of our earlier result that a standard regularization algorithm can be learned from examples. It illustrates that the natural constraints needed to solve a problem in inverse optics can be extracted directly from a sufficient set of input data and the corresponding solutions. The learning procedure has been implemented as a parallel algorithm on the Connection Machine System
Associative learning of standard regularizing operators in early vision by Massachusetts Institute of Technology( Book )

1 edition published in 1984 in English and held by 1 WorldCat member library worldwide

Spotlight on attention by Anya Hurlbert( Book )

1 edition published in 1985 in Undetermined and held by 0 WorldCat member libraries worldwide

Abstract: "We review some recent psychophysical and anatomical data which highlight the important role of attention in visual information processing, and discuss the evidence for a serial spotlight of attention. We point out the connections between the questions raised by the spotlight model and computational results on the intrinsic parallelism of several tasks in vision."
